The Impact of Beamwidth on Temporal Channel Variation in Vehicular Channels and its Implications
Vutha Va, Junil Choi, Robert W. Heath
Millimeter wave (mmWave) has great potential in realizing high data rate thanks to the large spectral channels. It is considered as a key technology for the fifth generation wirele…
Millimeter-wave Gbps Broadband Evolution towards 5G: Fixed Access and Backhaul
Zhouyue Pi, Junil Choi, Robert Heath
As wireless communication evolves towards 5G, both fixed broadband and mobile broadband will play a crucial part in providing the Gbps infrastructure for a connected society. This…
Near Maximum-Likelihood Detector and Channel Estimator for Uplink Multiuser Massive MIMO Systems with One-Bit ADCs
Junil Choi, Jianhua Mo, Robert W. Heath
In massive multiple-input multiple-output (MIMO) systems, it may not be power efficient to have a high-resolution analog-to-digital converter (ADC) for each antenna element. In thi…
Exploiting the Preferred Domain of FDD Massive MIMO Systems with Uniform Planar Arrays
Junil Choi, Taeyoung Kim, David J. Love +1
Massive multiple-input multiple-output (MIMO) systems hold the potential to be an enabling technology for 5G cellular. Uniform planar array (UPA) antenna structures are a focus of…
